+ | DESCRIPTION |
+ I tried to install the game Zork : Grand Inquisitor ( probably a win16 app) and
+ the installer crashed.
+ With the debugger, I Obtained the attached log.
+
+ As you can see
+ 1) CreateWindowExA is called (9170)
+ 2) X11DRV_CreateWindow send the WM_CREATE message to the window (9168)
+ 3) the window procedure of the app is executed (9162) and call
+ SetForegroundWindow (9161)
+ 4) WINPOS_SetActiveWindows is then called (9160) and send the WM_QUERYNEWPALETTE
+ (9159)
+ 5) When the windows procedure receive the message (9153), it call
+ SetForegroundWindow (9152)
+ 6) return to 4
+
+ Commenting the lines (see attached diff) in winpos.c wich send the
+ WM_QUERYNEWPALETTE avoids
+ the infinite loop and makes the installer work.
+ The installer runs perfectly under Windows 98.
+
+ It seems that the app's windows procedure does not expect a WM_QUERYNEWPALETTE
+ message.
